Returns:

The <clickChar> <function> <return|returns> a <character>.

Description:

Use the <clickChar> <function> within a <mouseDown>, <mouseUp>, or

<selectionChanged> <handler> to determine which <character> the user

clicked, in order to provide <hypertext> (clickable text) or take some

action based on the clicked <character>.

The <clickChar> <function> is cleared at the next mouse click, as well

as after some editing actions such as deleting text. If the last click

was not in a <field>, the <clickChar> <function> <return|returns> empty.

If the field is locked, the <clickChar> function is most useful within a

<handler> (such as <mouseDown> or <mouseUp>) that is <trigger|triggered>

by the mouse click.

If the field is unlocked, mouseDown and <mouseUp> <message|messages> are

not sent when the user clicks in the <field> (unless the user

right-clicks or holds down the Control key while clicking). Use the

<clickChar> <function> within a <selectionChanged> <handler> to

determine what <characters> the user is editing in an <unlock|unlocked>

<field>.

To find the position of the <clickChar>, use the <clickChunk>

<function>.
